Winamac WWTP - Pulaski County, Indiana Wastewater Treatment Plant

Winamac WWTP is a municipal wastewater treatment facility located on US 35 in Pulaski County, Indiana. The plant serves a population of about 2,534 people, classifying it as a small agglomeration under US regulatory standards. As a US facility, Winamac WWTP operates under the Clean Water Act, with National Pollutant Discharge Elimination System (NPDES) permits issued by the Indiana Department of Environmental Management. These permits set effluent limits to protect water quality. Plants of this scale typically employ secondary treatment to meet federal standards. The plant's treated effluent discharges into local streams that flow into the Tippecanoe River, part of the Wabash River watershed, which ultimately drains to the Mississippi River and the Gulf of Mexico. This connection underscores the plant's role in maintaining water quality in a region known for agricultural activity and diverse aquatic habitats.

The treated effluent from Winamac WWTP enters local tributaries of the Tippecanoe River, which flows into the Wabash River, a major tributary of the Ohio River and ultimately the Mississippi River. This watershed supports diverse aquatic life, including fish species such as bass and catfish, and provides habitat for migratory waterfowl. The plant's discharge must comply with state water quality standards to protect these ecosystems.
